The 1200 Series self-aligning ball bearings feature a double-row design with a spherical outer ring raceway, enabling automatic compensation for shaft misalignment up to 3 degrees. The cylindrical bore and compact dimensions make these bearings ideal for light to medium load applications. Widely used in agricultural machinery, textile spinning frames, conveyor systems, and ventilation fans where shaft deflection or mounting errors are common.
